2009 Chevrolet Suburban 1500 Throttle Body

While depressing the lock, remove the connector from the component. Then you should locate the two indents of the terminal position assurance (TPA), raise the TPA on both sides of the connector, view the TPA when removed from the connector body, release the terminals, and move the terminal release to the right. While holding the removal tool in place, you should gently pull the wire out of the back of the connector. Always remember never to use force when pulling a terminal out of a connector.

You need J 36169-A Fused Jumper Wire.

You should slide the lever lock forward while pressing down on the lever lock release tab, disconnect the connector from the component, and locate the dress cover locking tabs at the corners of the dress cover. Use a small flat-blade tool to release the locking tabs and remove the dress cover, and use a small flat-blade tool to slide the terminal position assurance (TPA) up one notch on both ends of the connector. While holding the removal tool in place, you should gently pull the wire out of the back of the connector. Always remember never to use force when pulling a terminal out of a connector.

You should install the throttle body gasket to the intake manifold, align the tab of the gasket with the notch in the manifold, install the throttle body, bolts, and nuts, connect the engine wiring harness electrical connector to the electronic throttle control, install the air cleaner outlet duct, connect a scan tool to test for proper throttle-opening and throttle-closing range, operate the accelerator pedal and monitor the throttle angles, verify that the vehicle, perform the Throttle Learn Procedure and inspect for coolant leaks.

The engine control module (ECM) learns the airflow through the throttle body to ensure the correct idle. The learned airflow values are stored within the ECM. These values are learned to adjust for production variation and will continuously learn during the life of the vehicle to compensate for reduced airflow due to throttle body coking. Anytime the throttle body airflow rate changes, for example, due to cleaning or replacement, the values must be relearned. An engine that had a heavily coked throttle body that has been cleaned or replaced may take several drive cycles to learn out the coking. To accelerate the process, the scan tool can reset all learned values back to zero. A new ECM will also have values set to zero. The idle may be unstable or a DTC may be set if the learned values do not match the actual airflow.
